Hyper Threading Function
This field is used to enable or disable the Hyper Threading function. Setting to [Enabled]
will increase the system performance. Settings: [Enabled], [Disabled].
MPS Revision
This field allows you to select which MPS (Multi-Processor Specification) version to
be used for the operating system. You need to select the MPS version supported by
your operating system. Settings: [1.4] and [1.1].
APIC ACPI SCI IRQ
This field allows you to specify which IRQ is used for ACPI SCI.
CPU L1 & L2 Cache
Cache memory is additional memory that is much faster than conventional DRAM
(system memory). When the CPU requests data, the system transfers the requested
data from the main DRAM into cache memory, for even faster access by the CPU. The
setting controls the internal cache (also known as L1 or level 1 cache). Setting to
[WriteBack] will speed up the system performance.
System BIOS Cacheable
Selecting Enabled allows caching of the system BIOS ROM at F0000h-FFFFFh, re-
sulting in better system performance. However, if any program writes to this memory
area, a system error may result. Setting options: [Enabled], [Disabled].
